Vraylar vs Seroquel
Introduction
For patients with bipolar disorder, schizophrenia or other severe mental health conditions, certain drugs that alter the balance of chemicals in the brain related to mood and perception can help manage symptoms. Vraylar and Seroquel are two such medications frequently prescribed for these disorders. They each affect different neurotransmitters in the brain but both have a stabilizing effect on patients' mood and perceptions. Vraylar is classified as an atypical antipsychotic, affecting levels of dopamine and serotonin through partial agonism. On the other hand, Seroquel is also an atypical antipsychotic but works mainly by antagonizing various receptors including those for serotonin and dopamine.
What is Vraylar?
Cariprazine (the generic name for Vraylar) is an atypical antipsychotic which was a significant progression from the first class of antipsychotic drugs. Cariprazine was approved by the FDA in 2015, and it's designed to treat certain mental/mood disorders such as bipolar disorder and schizophrenia. Similarly to Prozac, Vraylar works by helping restore the balance of certain natural substances in the brain. It functions by blocking or lessening the effects of dopamine in the brain, effectively "trapping" it longer than usual.
On another spectrum, Quetiapine (Seroquel), another atypical antipsychotic drug used for similar conditions as Vraylar, operates slightly differently. Seroquel also influences serotonin levels but has a broader effect on multiple neurotransmitters including dopamine too.
Both medications have their own unique side-effects profile that patients should be aware about before starting treatment. A key difference between these two is that while Seroquel impacts both serotonin and dopamine receptor sites more broadly leading to potential more side effects; Vraylar acts selectively mainly on dopamine receptors resulting in fewer undesirable side-effects.
What conditions is Vraylar approved to treat?
Vraylar is approved for the treatment of several psychological disorders:
- Schizophrenia, a chronic and severe mental disorder affecting how a person thinks, feels, and behaves
- Bipolar I disorder (manic or mixed episodes)
- Depressive episodes associated with bipolar I disorder as monotherapy or in combination with lithium or valproate.
How does Vraylar help with these illnesses?
Vraylar helps manage symptoms of bipolar disorder and schizophrenia by balancing dopamine and serotonin levels in the brain. It does this by acting as a partial agonist at certain receptors, which means it partially activates these receptors while also blocking them from being fully activated or deactivated by other chemicals. Dopamine and serotonin are neurotransmitters that play pivotal roles in mood, cognition, reward-driven behavior, and perception of reality among other things. In conditions such as bipolar disorder or schizophrenia, there is thought to be an imbalance in these neurotransmitter systems. By modulating the activity at these receptor sites, Vraylar can help stabilize mood swings associated with bipolar disorder and alleviate psychotic symptoms seen in schizophrenia.
What is Seroquel?
Seroquel, the brand name for quetiapine, is a second-generation antipsychotic drug that works as a dopamine, serotonin and adrenergic antagonist. This means it blocks the action of these neurotransmitters in the brain. Quetiapine was given approval by FDA in 1997. Unlike Vraylar (cariprazine), which is a partial agonist at certain dopamine receptors and acts on both D2 and D3 receptors selectively, Seroquel inhibits several different neurotransmitter receptors including those for dopamine and serotonin.
Its broad-spectrum receptor blocking profile makes it effective not only against schizophrenia but also against depressive episodes linked to bipolar disorder or major depressive disorder when used with an antidepressant. It's important to note that while its therapeutic effects can be beneficial, Seroquel may also cause side effects like sedation (which is less common with Vraylar) along with weight gain and metabolic changes such as increased cholesterol levels – so patient monitoring during treatment is key.
What conditions is Seroquel approved to treat?
Seroquel is approved by the FDA for use in treating:
- Schizophrenia
- Acute manic episodes associated with bipolar I disorder
- Depressive episodes associated with bipolar disorder Furthermore, it can also be used as an add-on treatment for patients suffering from major depressive disorders.
How does Seroquel help with these illnesses?
Seroquel is an atypical antipsychotic that works by affecting the actions of certain chemicals in the brain, including serotonin and dopamine. Dopamine plays a significant role in motivation, reward, and how we perceive reality while serotonin influences mood, appetite, sleep, memory and learning. Seroquel's impact on these neurotransmitters can help alleviate symptoms of schizophrenia and bipolar disorder such as hallucinations or mania. Like Vraylar, Seroquel also treats both manic and depressive episodes associated with bipolar disorder but may be chosen over other medications due to its additional FDA approval for use as maintenance treatment (when combined with antidepressants) in bipolar disorder to prevent mood swings. Its sedative effects make it beneficial for those struggling with insomnia related concerns as well.
How effective are both Vraylar and Seroquel?
Both cariprazine (Vraylar) and quetiapine (Seroquel) have been effectively used in managing symptoms of bipolar disorder and schizophrenia, approved by the FDA several years apart. They work on different neurotransmitter systems; therefore, they might be prescribed under varying conditions. The effectiveness of Vraylar and Seroquel in treating schizophrenia was directly compared in a 2013 double-blind clinical trial; both drugs showed similar efficacy in controlling symptom severity alongside comparable safety profiles. No significant difference was observed between patients receiving Vraylar or those treated with Seroquel regarding various metrics used to measure the progression of their condition.
A review from 2016 highlighted that cariprazine is effective immediately after starting treatment for schizophrenia or mania associated with bipolar I disorder. Its side effect profile compares favorably against many other antipsychotics, tolerable even amongst older populations. As one of the newer atypical antipsychotic medications developed, there's an ongoing study into its effectiveness across multiple mental health conditions.
A 2008 meta-analysis suggested that quetiapine appears more potent than placebo treatments for bipolar depression while exhibiting similar efficacy to other common antipsychotics. Nevertheless, quetiapine is often considered as a second-line option after initial mood stabilizing treatments have proved unsuccessful due to potential side effects like weight gain and sedation associated with its use. Significant data surrounding its usage involves studies where it has been co-administered along with another first-line treatment drug; thus data confirming its stand-alone efficiency are less robust than that for cariprazine.
At what dose is Vraylar typically prescribed?
Oral dosages of Vraylar range from 1.5-6 mg/day, with studies indicating that 1.5 mg/day is often sufficient for treating bipolar disorder or schizophrenia in most people. Children and adolescents may be started on lower doses as determined by a physician. In either population, the dosage can be increased after a few weeks if there is no response. The maximum dosage that should not be exceeded in any case is 6 mg/day.

At what dose is Seroquel typically prescribed?
Seroquel treatment is typically initiated at a dosage of 25 mg/day. The dose can subsequently be increased to 300-400 mg/day, divided into two doses, spaced approximately 12 hours apart. The maximum dose is generally around 800 mg/day administered in two or four divided doses, which may be considered if there's no significant response to lower dosages after several weeks. It's important to remember that these are general guidelines and the precise dosage should always be determined by a healthcare professional based on individual patient needs.
What are the most common side effects for Vraylar?
Common side effects of Vraylar include:
- Insomnia and restlessness
- Weight gain
- Uncontrolled movements, such as tremors or shaking
- Nausea, vomiting, stomach upset
- Constipation
- Dizziness upon standing (orthostatic hypotension)
- Dry mouth
On the other hand, common side effects of Seroquel include:
- Drowsiness and sedation
- Increased appetite leading to weight gain
- Dry mouth
- Constipation
- Upset stomach or indigestion
-Dizziness and lightheadedness which can lead to falls in older adults.
Please note that these are only potential side effects. Not everyone who takes these medications will experience these adverse reactions. If you have any concerns about your medication’s side effects, it's important to consult with a healthcare professional immediately.
Are there any potential serious side effects for Vraylar?
In rare instances, Vraylar can cause serious side effects, which include:
- Increased thoughts about suicide or self-harm
- Signs of an allergic reaction or severe skin reaction: symptoms such as hives; difficulty breathing; swelling in your face, throat or tongue; fever; sore throat; burning sensation in the eyes; skin pain and rashes that are red or purple with blistering and peeling.
- Vision problems including blurred vision, tunnel vision, eye pain/swelling and seeing halos around lights.
- Cardiovascular issues like rapid heartbeats, fluttering sensations in your chest leading to shortness of breath. These may be accompanied by sudden dizziness (feeling like you might faint).
- Low sodium levels resulting in headaches, confusion/slurred speech, intense weakness/lethargy/vomiting. This could lead to loss of coordination making one feel unsteady.
- Severe nervous system reactions causing very stiff (rigid) muscles/high fever/excessive sweating/confusion/fast uneven heartbeats/tremors/feeling as though you might pass out.
It's vital that if any of these symptoms present themselves after taking Vraylar it is stopped immediately and medical assistance sought promptly.
What are the most common side effects for Seroquel?
Seroquel, much like any other medication, may cause several side effects. These can include:
- Dry mouth and increased thirst
- Stuffy nose or nasal congestion
- Blurred vision
- Nausea, upset stomach, constipation
- Sleep disturbances (either insomnia or excessive sleepiness)
- Signs of nervousness such as sweating and anxiety
- Changes in heart rhythm including a fast heartbeat
- Mood changes: agitation or sudden aggressive behavior
- Unusual skin reactions such as rash
- Weight gain instead of weight loss is commonly observed with Seroquel use
- More frequent urination than usual
- Headaches or dizziness,
- Muscle stiffness and occasional joint pain.
It's important to remember that not all patients will experience these side effects while using Seroquel; these are potential risks associated with the medication. Always consult your healthcare provider if you're experiencing uncomfortable symptoms.
Are there any potential serious side effects for Seroquel?
While Seroquel is typically well-tolerated, it can potentially cause serious side effects. These include:
- Signs of an allergic reaction such as hives, difficulty breathing, and swelling in your face or throat
- Symptoms suggestive of high blood sugar levels like increased thirst, frequent urination, dry mouth, fruity breath odor
- Uncontrolled muscle movements which may become irreversible over time
- Lightheadedness or fainting spells caused by a sudden drop in blood pressure when standing up from sitting or lying position
- Increased heart rate or irregular heartbeat; chest pain
- Severe nervous system reaction with symptoms including very stiff (rigid) muscles, high fever, sweating, confusion and fast or uneven heartbeats
- New mental/mood changes like depression thoughts about suicide
If any of these symptoms occur while taking Seroquel immediately contact your healthcare provider to evaluate the need for continued treatment versus potential risks.
Contraindications for Vraylar and Seroquel?
Both Vraylar and Seroquel, like many other antipsychotic medications, may potentially exacerbate symptoms of depression in some individuals. If you notice a worsening of your depression or an increase in suicidal thoughts or behaviors while taking these drugs, it is crucial to seek immediate medical attention.
Neither Vraylar nor Seroquel should be taken if you are currently using, or have recently stopped taking cytochrome P450 inhibitors (CYP3A4 inhibitors). It's essential to keep your physician informed about all the medications you are on; CYP3A4 inhibitors will require a period of approximately 1 week to clear from your system before starting treatment with either Seroquel or Vraylar in order to prevent dangerous drug interactions.
How much do Vraylar and Seroquel cost?
For the brand name versions of these drugs:
- The price for 30 capsules of Vraylar (3 mg) averages around $1,350, which works out to approximately $45/day.
- The price for 60 tablets of Seroquel (100 mg) is on average about $900, equating to roughly $15/day.
Thus, if you are taking a standard dosage range for both medications(i.e., up to 6 mg/day for Vraylar and up to 800mg/day for Seroquel), then brand-name Seroquel is less expensive on a per-day treatment basis. However, cost should not be the primary consideration in determining which drug is right for you.
As far as generic versions go:
- Quetiapine Fumarate (generic version of Seroquel) comes in varying quantities with costs ranging from approximately$0.67 - $2.00 per day depending upon dosage and quantity bought at one time.
The situation differs with Vraylar; there's currently no generic equivalent available making it significantly more costly than its counterpart.
Popularity of Vraylar and Seroquel
Cariprazine, also known by the brand name Vraylar, was estimated to have been prescribed to approximately 540,000 people in the US in 2020. Cariprazine accounted for nearly 2% of atypical antipsychotic prescriptions in the US. Despite being a newer medication with approval from FDA only since 2015, it has seen a steady increase in prescription rates.
Quetiapine, including its popular brand version Seroquel, was prescribed to about 7 million people in the USA during that same time period. In terms of total atypical antipsychotic prescriptions within the country, quetiapine accounts for just over one-third. The prevalence of quetiapine usage has been consistently high over recent years due to its broad range of indications – not just schizophrenia and bipolar disorder (which are common uses for many drugs in this class), but also major depressive disorder as an adjunctive therapy.
Conclusion
Both Vraylar (cariprazine) and Seroquel (quetiapine) are used in the management of psychiatric conditions such as schizophrenia and bipolar disorder. Their effectiveness is supported by various clinical studies, showing they often perform better than placebo treatments. The two drugs may sometimes be used together under careful physician supervision, but this is not typically a first choice due to potential for drug interactions.
Vraylar primarily works through affecting dopamine and serotonin receptors, whereas Seroquel also affects histamine and adrenergic receptors alongside its action on dopamine and serotonin. As a result of these differences in mechanisms of action, they tend to be prescribed under different circumstances.
Seroquel has been around longer than Vraylar which makes it available in generic form representing significant cost savings especially for patients who must pay out of pocket. However, both medications can take several weeks to show full effects so an adjustment period might be necessary when starting treatment with either medication.
While the side effect profiles are similar between the two drugs with common reports including drowsiness or sedation, weight gain, dry mouth among others; some side effects like extrapyramidal symptoms - movement disorders that include stiffness or restlessness - may occur more frequently with Vraylar compared to Seroquel. Both medications require regular monitoring due to their potential mental health impact; any worsening mood or suicidal thoughts should prompt immediate medical attention.
